With the Whats In app you can browse a collection of recipes around the internet from the best websites, same as any other app, but the killer feature offered here is being able enter the ingredients you have in your home and have the app show you the matched recipes you can make right now!
The app will also suggest recipes you can make if you could pop to the shop and pick up 1 or 2 ingredients (or just forgot to add them to your list), offering you an even wider selection.
